COMBINED STEAM AND HOT-AIR HEATING SYSTEM FOR BUILDINGS.

Application filed May 1, 1917.

To all whom it may concern:

Be it known that I, CHARLES R. HANSEN, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Combined Steam and Hot-Air Heating Systems for Buildings, of which the following is a specification.

This invention relates to an improvement in combined sanitary steam and air heating systems for buildings, and is especially adapted for use in heating cottages, bungalows, store buildings, apartments and residenees of the medium size construction ineluding from six to eight rooms.

The main object of this invention is to provide a novel, simple, durable, economical and efficient sanitary means for heating and ventilating buildings which an be readily operated by anyone who can tell when the water gets low in the water gage carried by the furnace.

' Another object of the invention is to provide a heating system which includes the entrance of fresh air at the floor portion of a hot air room through the hollow wall forming one side of said room, which air becomes warmed by contact with the inner wall of the room before its entrance therein, the air then being highly heated, disinfected and purified by the means hereinafter described, said means being fixed and suspended in the hot air room, from which room the air is forced by suitable distributing pipes and an electrically operated fan to the various rooms or apartments.

The foregoing and such other objects as mayappear from the ensuing description are attained by the novel features of construction, combination, arrangement and lo cation of the parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the laims appended hereto, it being understood that slight ehanges in the form, proportions, and minor details of the construction may be resorted to without departing from'the spirit or sacrificing any of the advantages of the invention;

In the accompanying drawings, which form a part of-this specification, it will be seen that I Figure 1, is a perspective view illustrating the improvements embodying my invention.

Fig. 2, is a longitudinal sectional view through an air vent of the steam radiators.

Specification of Letters Patent.

Serial No. 165,755.

Fig. 3, is a plan view of the air moistening coil which is suspended around the steam radiator, and Fig. l, is a perspective-view of the air disinfecting and purifying drum or tank which is suspended around the heating furnace.

Similar letters of reference are employed to designate corresponding parts throughout the several fi ures of the drawings.

In the embodiment of my invention as illustrated and whiehshows a preferred construction, A indicates the hollow wall forming one side of the hot air room B, the fresh air being led into the hollow wall through the inlet A passes downward therein becomes warmed or partially heated in its passage by contact with the inner wall B of the hot air room and is caused to emerge into said room through a series of openings 9 formed in the lower or bottom portion of said inner wall B.

Suitably located within the air room, as

shown in Fig. 1,.is a steam boiler furnace an adapted to radiate the heat therefrom in heating the air, which heat otherwise goes to waste, and connected to said boiler furnace is a smoke flue a which leads to a counter-heater b intended to utilize all of the heat that usually passes out of the chimney in heating the air within the air room, said counter-heater being connected with a pipe Z) leading to the chimney and provided with caps (Z which may be removed for cleaning purposes and readily replaced. Connected to the upper portion of the boiler furnace is a water gage e and a steam gage c which are adapted to be extended outside of the front wall so as to be visible at all times.

C, designates a steam heated coil which is suspended near the ceiling by rods 0, e, which are igidly but removably secured to a supporting bar In, carried by the ceiling, said coil C being connected to the upper part of the boiler, and 7 indicates a coil box or casing made of sheet iron suitably supported at the ceiling which easingis open at its bottom portion for the purpose of leading the air in the room to its last and final heating before it is distributed to the rooms or apartments above. Located within said box or casing is a series of steam heated radiators, or section coils 0 adapted to further heat the air which is led into the casing by the electrically operated fan Z before the heated air is forced by the said fan to the rooms or apartments through the main distributing pipe S, said radiator sections or coils 0 being suitably connected with the upper part of the boiler furnace.

As shown in Fig. 1 a cast iron plate h is utilized for bridging or supporting a con-v tinuation of the brick work construction above the fire-place, and the main distributing pipe S, may be provided with any suitable number of branch pipes 71, leading to the several rooms or apartments and through which the hot air from the hot air room is distributed. a r

. lhe boiler furnace is supplied by water fed thereto through the supply pipe p connected to any suitable or desirable source of water supply, which pipe 39 is provided with a valve 2.

Within each upper head portion of the steam heated radiator sections 0 is a cylindrical member Y secured to said head portion, and within said member is fitted a hollow cylindrical valve 2 having an outlet u communicating with the air-vent U which extends from each of the sections 0, said valve 2, being provided at one end thereof with an outwardly extending stem .2 to the outer end portion of which is suitably secured an upwardly projecting arm w, as shown in Fig. 2, each of the arms w being connected by a horizontally arranged bar '20, one end of thebar being connected to an operating wire or chain '0 leading to a suitable room or apartment, and the other end of the bar being connected to a wire, cord, or chain c, to which a weight 8 is attached at its outer end, whereby a slight pull on the operating wire or chain will move the horizontal bar laterally thus causing the outlet in each valve to register with each air vent thereby permitting the air to be freely vented and to escape from the radiator sections, and whenthe operating rope is re leased the weight will move the said bar in the opposite direction thereby closing the air vents. It Will be seen that the said horizontal bar w may be provided with a notched or toothed section 8, adapted to engage with a pawl or catch 25 for the purpose of holding the vents in open or closed position as long as desired, said catch or pawl being connected with an operating wire or chain t.

In the wall of each room or apartment is suitably located a hot air inlet register at, a cold air outlet register m communicating with the hot air room, and a foul air outlet register m connected with a foul air flue.

Suitably suspended in a level horizontal position in the casing f, and surrounding the radiator section, is an air moistening or disinfecting device 9%, consisting of a series of pipes connected together, each pipe and its connection being perforated through its upper portion, said moistener having a funnel shaped connection 7" through which the water or other liquid is fed into the said moistener, and suitably secured around the boiler furnace in any desirable position, is a roundly shaped tank 11, having a vertical inner and outer wall and provided with a series of openings in and near its upper end portion and thus start the electrically operated fan,

thereby stirring and circulating the air in the room, and if there is any heat in the hotair room itis immediately forced into the room, then by shaking the fire in-the boiler furnace, opening the draft, and adding fresh fuel steam will soon be generated and the air will become suitably heated for its discondition. y i

. It will be perceived that thechill of the 'tribution throughout the building, and can be economically'maintained in its heated fresh air is removed and the air partially v heated before its contact with the steam pipes thereby saving considerable steam which means a saving of fuel.

The safety valve 9 connected to the top of the boiler furnace may be set at 15 lbs. since 5 lbs. of pressure is all that is usually re--.

quired for a six or sevenroom house.

In cases of sickness the air; may be'purified, sweetened or disinfected by the use of a proper solution poured into either or both the device a, and the tank n and it will be readily seen that the system hereinbefore described is an efficientone for the economical sanitary heating and ventilating of the rooms or apartments of buildings, and it is thought that the construction and operation of my improved system Will be readilyunderstood without further description per-- taining thereto.
